FORGE.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed March 6, 1905. Serial No. 248,681.

To all whom it may concern.-

Be it known that I, WILLIAM F. WENDT, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Forges, of which the following is a specification.

This invention relates to blacksmiths forges, and more particularly to the portable kind which are set up in the shop or room at adistance from the chimney and are provided with hoods for catching and directing the smoke and gases from the fire to the smoke-pipe. These hoods are usually faulty or objectionable, in that they either fail to properly catch and carry off the smoke and gases arising from the fire or, on the other hand, if they are properly shaped and located to carry off all of the smoke and gases they so obstruct the hearth of the forge as to materially interfere with the blacksmiths operations.

The objects of the invention are to provide a forge with means which will efliciently catch and carry off the smoke and gases without obstructing the hearth or fireplace and to so construct and arrange the hood or smoke-catcher that it will operate to catch and carry off the smoke and gases either with or without means for creating a forced draft in the smoke-flue.

In the accompanying drawings, consisting of two sheets, Figure 1 is a fragmentary perspective view of a forge embodying the invention. Fig. 2 is a fragmentary plan view thereof, partly in horizontal section, in line 2 2, Fig. 4:. Fig. 3 is atransverse sectional elevation through the upright smoke-flue in line 3 3, Fig. i. Fig. 4 is afragmentary longitudinal sectional elevation of the forge.

Like letters of reference refer to like parts in the several figures.

The forge, which may be either of the stationary or portable type, has a hearth A of any usual or suitable formand construction, which is supported by,legs a or some other kind'of base.

B represents the usual fireplace in the hearth provided with a blast-twyer b, and O represents a fan-blower or air-forcing device, the air-discharge or blast pipe 0 of which connects with the twyer Z). The blower may be of any usual form and operated by any suitable means.

D represents the smoke hood or catcher,

which is arranged above the hearth and overhangs the fireplace B. The hood is preferably of the hollow rectangular shape shown, having a horizontal top with depending front and side walls and is supported by an upright back 6, which rests on or is secured to and rises from the hearth in rear of the fireplace. The back 6 of the smoke-hood is hollow, forming an ascending smoke-flue F, provided in its front wall witha smoke-inlet openingf, which is located just in rear of the fireplace B and only a short distance above the hearth. The upper open end of the smoke-flue F enters or communicates with a smoke-pipe G, which leads from the top of the hood D to the chimney. The hood also opens into the lower end of the smoke-pipe independently of the upright smoke-flue, so that the smoke and gases from the fire can pass into the smoke-pipe either directly from the hood or indirectly by way of the inlet-openingf and upright flue F. The flue could, if desired, be formed by a separate pipe occupying the same position as the hollow back of the hood.

H represents a shield or auxiliary hood which projects forwardly from the upright smoke-flue F above the inlet-openingf thereof and beneath the main hood D. The shield .or auxiliary hood H is preferably smaller than the main hood and adjustably mounted so that its position or inclination can be adjusted to properly direct the smoke and gases into the inlet-opening f. In the construction shown the shield is hinged at the front side of the upright flue F, and its hinge pin or shaft is extended through the side of the hood and provided with an operating-arm h, furnished with any suitable means It for releasably holding it and the shield in adjusted positions.

Preferably the-eye or intake of the blower G is connected with the lower end of the upright smoke-flue F by a suction-pipe I, and a branch pipe K discharges a portion of the airblast from the blower into the smoke-pipe G to induce an upward draft therein. The open upper end of the branch pipe K preferably terminates-in the smoke-pipe substantially at the upper end of the upright smoke-flue F and also creates an induced draft in the latter. The separate pipe K (shown in the drawings) or a flue partitioned off in the upright smokeflue can be employed for this purpose. By reason of the described arrangement of the suction and blast pipes of the blower a portion of the smoke and gases is drawn into the blower and returned to the fire and a portion passes upwardly into the smoke-pipe under the influence of the induced draft therein. The proportion of these parts can be regulated, if found necessary, by providing the suction and blast pipes with dampers.

The operation of the forge is as follows: When a green fire is started and the blower is operated at a comparatively slow speed, the dense smoke generated is drawn into the inlet-opening f of the upright flue F by the suction and induced draft in the latter caused by the blower. The smoke from the extreme front end of the fire will be caused to hover close to the coal and travel rearwardly into the inlet-opening. None, or at least only an inconsiderable portion, of the smoke and gases will escape past the shield H, but that which does will be caught by the hood and drawn into the open lower end of the smoke-pipe. With only the main hood D opening so far above the hearth as it should in order not to interfere with the blacksmiths operations it 'would be impossible to create the necessary suction at the fire to hold this smoke and prevent its escape into the room or shop. Then as the speed of the blower is increased and the volume of dense smoke and gases is considerably augmented only a portion thereof will pass up through the upright smoke-flue F and the remainder will be caught by the main hood D and pass directly up into the smoke-pipe G. Under these conditions without the large main hood D a large volume of the smoke and gases would escape into the shop. Thus neither the main hood nor the upright fine with the shield H alone will properly take care of the smoke and gases, and the two associated as described are necessary to a realization of the desired result. Later when the coal becomes coked the flame and gases will pass out through the opening f and upright flue F. When the blower is out of action, the draft created by the chimney will take care of the smoke and gases arising from the fire.

While greater perfection of operation of the forge will result from the use of the suction and blast pipes I and K, as described, the main hood or smoke-catcher with the upright smoke-flue and shield or auxiliary hood when used independently of the suction and draft inducing means are a marked improvement over a single hood in either the location of the main hood D or auxiliary hood H.

L, Fig. 4, represents a plate or apron hinged to the hood D and adapted to be turned down, as indicated by dotted lines in Fig. 1, when starting a fire or to be turned up out of the way after the fire is started. Such .plates may, if desired, be provided at the front and one side of the hood; but they are not essential to the proper operation of the forge.

I claim as my invention 1. The combination of a hearth having a fireplace, a smoke-hood above the hearth, a smoke-pipe ascending from said hood, and an ascending smoke-flue which has a smoke-inlet opening located adjacent to the fireplace, said fine connecting at its upper portion with said smoke-pipe, substantially as set forth.
